Doesn't seem to work with Snow Leopard - at least for many users - unless you downgrade to an earlier version of Flip4Mac (according to the Switch support forums.) All2MP3, also freeware, doesn't have that problem, and works well with WMA (as well as other formats.)

To decompress FLACs, I first used Switch based on the numbers of users it got here, but unfortunately, switch cannot decompress 24bit 96kHz FLACs into its proper uncompressed counterpart - it creates a 16bit file. So I'm now using XLD.

1.50 is downloaded. Not 1.52.

mac version doesn't support aac, mp2, m4a or amr

Great app but would be great if they added a context (right-click) menu item in Finder/Forklift/Pathfinder/++ for quick conversion based on a preset in the preferences or something.

I'm never very happy when I realize I need this application, but the fact of the matter is that it's the best solution available. I recommend converting to CBR mp3s, because converting to VBR often results in crashes.

This app is excellent. Quick, simple and straight forward.

I tried Tune4Mac from http://www.tune4mac.com and it is super fast because it uses a Virtual CD burning method to convert M4P to MP3.
